Description

  The present invention relates to a partition box provided with a partition plate and a packaging box. More specifically, the present invention relates to a partition box that can reduce the number of partition plates and can be easily assembled.

  Conventionally, packaging boxes such as corrugated cardboard have been used to transport goods and the like. And when packaging several goods collectively in a packaging box, in order to prevent the damage by the collision of goods, the partition box which provided the partition plate is used.

  A generally used divider box 100 is shown in FIG. The partition box 100 includes a packaging box 200 and a partition plate 300 housed therein, and the partition plate 300 is formed by assembling a plurality of partition plates into a lattice shape. In the example of the partition box 100 shown in FIG. 20, the partition plate 300 includes two vertical partition plates 301 and one horizontal partition plate 302, and is assembled in a lattice shape and then accommodated in the packaging box 200. It is.

  Since the partition box generally used needs to assemble a plurality of partition plates, there is a problem that the number of packing steps increases and workability is poor. Moreover, since there are many parts of a partition plate, the subject that the cost of a partition plate becomes high, the subject that inventory management of a partition plate becomes complicated, etc. also occur.

On the other hand, in order to solve the problem of such a general partition box, a partition box in which a partition plate is provided integrally with a packaging box is known.
For example, in Patent Document 1, a bottom forming piece and a first partition piece are provided on each side plate facing the packaging box via a fold line, and a bottom portion is similarly formed on each of the opposing side plates. In the partition box provided with the piece and the second partition piece, the first partition piece and the bottom forming piece describe a configuration in which a groove is formed from the middle part of the first partition piece to the folding line of the side plate. . In this partition box, the first partition piece and the second partition piece constitute a partition plate by bending the bottom forming piece and the second partition piece at right angles and inserting the second partition piece into the groove.

Although the partition box described in Patent Document 1 can integrally form a packaging box and a partition plate, there is a problem that processing of corrugated cardboard becomes complicated because of a complicated structure. In particular, the groove for fitting the second partition piece needs advanced processing to form a hole in the corrugated cardboard development view.
In addition, in the step of inserting the second partition piece into the groove, it is necessary to apply a load so that the second partition piece is curved somewhat. Therefore, there is a problem that the tip of the second partition piece is easily bent and is difficult to assemble.

The lower surface and the rear surface of the main body 41 are provided with printing surfaces 43a and 43b, and the cap 42 is provided with a claw portion 42a for opening.

  As for the shape of the article, like the article 40 of the embodiment, it is preferable that the width of the upper part is smaller than the width of the lower part, and the upper part is narrower than the lower part. When the partition plate 30 having the notched grooves 31a and 31b according to the present invention is used, the tip areas Ta and Tb of the flaps 24a and 24b functioning as the partition plates are installed in the packaging box 20 in an inclined state. Therefore, a space for accommodating the tip areas Ta and Tb of the flaps 24a and 24b is required. By forming the shape of the article so that the upper part is thinner than the lower part, even if a plurality of articles 40 are accommodated in the packaging box 20, a space is formed between the articles 40 in the upper part of the packaging box 20, and the flaps are formed. The tip areas Ta and Tb of 24a and 24b can be accommodated.

Further, the width between the tips of the flaps 24a and 24b is designed to be smaller than the width of the lower part of the article 40, and when the article 40 moves upward, the peripheral surface of the article 40 comes into contact with the tip of the flap. It is preferable to adopt a simple configuration. Note that the width between the front ends of the flaps can be designed by adjusting the notch groove angle (θ) of the partition plate, the length of the front end region of the flaps, and the like.
With the above configuration, when a trouble such as the partition box falling over during packaging of the article occurs, the article is prevented from jumping out of the partition box, so that the article can be prevented from being damaged.

Further, when the article 40 is stored in the packaging box 20, the peripheral surface of the article 40 is in a position close to the tips of the flaps 24a and 24b, and the article 40 restricts the upward movement. Is preferred.
According to this, the vertical shaking of the article being transported is reduced, and damage to the article and rubbing with the packaging box or the partition plate can be prevented.

The material of the article of the present invention is not particularly limited, and examples thereof include plastics such as polyethylene terephthalate (PET), polypropylene (PP), and polyethylene (PE), earthenware, glass, and paper boxes. Of these materials, it is preferable to use PET.
PET is characterized by being easily noticeable when scratched, and it can be scratched only by rubbing against a packaging box such as cardboard or a partition plate. Therefore, the effect of the present invention that prevents rubbing between the article and the partition plate or the packaging box is more remarkably exhibited.

The flaps 124a and 124b are provided with slits 127a and 127b for engaging with the cutout grooves 131a and 131b of the partition plate 130, respectively.
When an article is accommodated in a state where the partition plate is inclined, there is a problem that the partition plate is bent by the article. However, since the partition plate can be fixed vertically by engaging the partition plate and the flap, it is possible to prevent the partition plate from being bent when the article is accommodated.

The slits 127a and 127b have wide-mouth structures 128a and 128b whose slit width is enlarged at the tips of the flaps. Accordingly, the flap insertion portions 125a and 125b can be easily inserted into the cutout grooves 131a and 131b of the partition plate 130, and the assembly is facilitated.
The structures of the wide-mouth structures 128a and 128b are not particularly limited as long as the slit width expands at the flap tip, but a configuration in which the groove width gradually increases toward the flap tip is preferable. As the shape for increasing the groove width toward the front end of the flap, the shape of the corner formed by the front end of the flap and the slit is cut into an arc shape or a straight line like the cutout groove 31 of the partition plate 30 described above. An inclined portion may be provided. Furthermore, it is preferable that this corner has inclined portions on both sides.

  As shown in FIG. 18, the lengths of the tip regions Ta and Tb of the flaps 124a and 124b are set so that the height position of the tips of the flaps reaches the vicinity of the bottom plate 122. Thereby, a flap functions as a partition plate and generation | occurrence | production of the abrasion by contact between articles | goods can be suppressed.

[Partition plate]
FIG. 17 illustrates the partition plate 130 of the second embodiment. The wide-mouth structure 132a is a structure in which a groove 133 is gradually enlarged by cutting off a corner 133a closer to the side than the side plate 121b in a straight line.
In addition, an opening 134 cut into a substantially rectangular shape along the printing surface of the article is formed at the bottom side of the partition plate.
